DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment

FIG. 1 is an illustration view showing an example of a configuration of an image forming system 10 according to the present invention. With reference to FIG. 1 , the image forming system 10 that is the first embodiment according to the present invention includes a plurality of image forming apparatuses 12 and an information processing apparatus 14. Each of the plurality of image forming apparatuses 12 is connected with other image forming apparatus(es) 12 and the information processing apparatus 14 communicably via a network 16 such as an internet or LAN. In addition, although an example of the image forming system 10 shown in FIG. 1 has a single information processing apparatus 14 is connected on the network 16, two or more information processing apparatuses 14 may be connected. Moreover, although illustration is omitted, each of the plurality of image forming apparatuses 12 is connected also to a facsimile communication network such as a PSTN (Public Switched Telephone Networks) and an IP network.

The information processing apparatus 14 shown in FIG. 1 is a general-purpose computer (user terminal) that a user of the image forming system 10 uses. For example, the information processing apparatus 14 may be a smartphone, desktop PC, note (laptop) PC, tablet PC, etc.

FIG. 2 is a block diagram showing electric structure of the information processing apparatus 14 shown in FIG. 1 . With reference to FIG. 2 , the information processing apparatus 14 of the first embodiment includes a CPU 22. The CPU 22 is connected, via a bus 20, with a RAM 24, an auxiliary storage 26, an input control circuit 28, a display control circuit 30 and a communication circuit 32. Moreover, the input control circuit 28 is connected with an input device 34, and a display 36 is connected to the display control circuit 30.

As the display 36, an LCD or EL (Electro-Luminescence) display may be used. The same is applied also to a display 72 described later.

The CPU 22 is in charge of overall control of the information processing apparatus 14. The RAM 24 is used as a working area and a buffer area for the CPU 22.

The auxiliary storage 26 is an HDD (hard disc drive), for example, and is an auxiliary memory that stores a control program for controlling, by the CPU 22, operations of respective components of the information processing apparatus 14, various kinds of data, etc. However, as the auxiliary storage 26, another nonvolatile memory such as an SSD, a flash memory and an EEPROM may be used instead of the HDD or together with the HDD. The same is applied also to an auxiliary storage 56 described later.

The input device 34 is a device for receiving an input operation of the user (user operation), and includes, for example, a touch panel, a keyboard, a computer mouse, etc. When the input device 34 is a keyboard, the input device 34 includes hardware operating buttons or operating keys (hardware keys). The touch panel is a general-purpose touch panel, and an arbitrary system, such as a capacitance system, an electromagnetic induction system, a resistance film system and an infrared system can be used. Moreover, the touch panel may be provided on a display surface of the display 36, or may be provided separately from the display 36. However, a touch display that a touch panel is integrally formed with the display 36 may be provided. When a touch panel is provided on the display surface of the display 36, a GUI (Graphical User Interface) including software keys (operating keys) such as icons is displayed on the display 36. In such a case, an input operation may be received via the GUI (operation screen). The same is applied also to an input device 70 described later.

In addition, the software key means a key or icon reproduced by software on the display surface of the display, for example. On the contrary, the hardware key means a key or push button provided as a physical device.

The input control circuit 28 outputs an operation signal or operation data according to an operation of the input device 34 to the CPU 22. For example, the input control circuit 28 applies a voltage or the like required for the touch panel included in the input device 34, and when a touch operation (touch input) is performed within a touch effective range of the touch panel, the input control circuit 28 outputs to the CPU 22 touch coordinate data indicative of a position of the touch input. Moreover, the input control circuit 28 outputs to the CPU 22 an operation signal or operation data according to an operation of the operating button or hardware key included in the input device 34. The same is applied also to an input control circuit 64 described later.

The display control circuit 30 includes a GPU, VRAM, etc., and the GPU generates, under instructions of the CPU 22, screen data for displaying various kinds of screens in the VRAM with using image generation data 304 a (see FIG. 9 ) stored in the RAM 24, and outputs the generated screen data to the display 36. For example, various operating screens etc. are displayed on the display 36. The same is applied also to a display control circuit 66 described later.

The communication circuit 32 is a communication circuit for connecting with the network such as a LAN and an internet. This communication circuit 32 is a wired communication circuit or a wireless communication circuit, and communicates via the network, according to instructions from the CPU 22, with an external computer of a further information processing apparatus 14 or a further image forming apparatuses 12, utilizing protocols such as TCP/IP. However, the communication circuit 32 can perform communication directly with the further information processing apparatus 14 or the further image forming apparatus 12 by a short-distance wireless communication etc. without using the network 16.

In addition, the electric structure of the information processing apparatus 14 shown in FIG. 2 is a mere example, and should not need to be limited to this.

Returning to FIG. 1 , the image forming apparatus 12 is an MFP (Multifunction Peripheral) that comprises a copy function, a print function, a scanner function, a facsimile function, etc. However, the image forming apparatus 12 should just be provided with the print function at least, for example, and thus may be a print device (printer).

FIG. 3 is a block diagram showing electric structure of the image forming apparatus 12 shown in FIG. 1 . With reference to FIG. 3 , the image forming apparatus 12 includes a CPU 52. The CPU 52 is connected, via a bus 50, with a RAM 54, an auxiliary storage 56, an image reading unit 60, an image forming unit 62, an input control circuit 64, a display control circuit 66, a communication circuit 68 and a facsimile communication unit 74. Moreover, an input device 70 is connected to the input control circuit 64, and a display 72 is connected to the display control circuit 66.

The CPU 52 is in charge of overall control of the image forming apparatus 12. The RAM 54 is used as a working area and a buffer area for the CPU 52. The auxiliary storage 56 is an HDD (hard disc drive), for example, and stores a control program for controlling, by the CPU 52, operations of respective components of the image forming apparatus 12, various kinds of data, etc. However, as the auxiliary storage 56, another nonvolatile memory such as an SSD, a flash memory and an EEPROM may be used instead of the HDD or together with the HDD.

The image reading unit 60 is provided with a light source, a plurality of mirrors, an imaging lens, a line sensor, etc. This image reading unit 60 exposes an original surface by the light source, and leads a reflected light reflected from the original surface to the imaging lens by the plurality of mirrors. Then, the reflected light is imaged on light receiving elements of the line sensor by the imaging lens. The line sensor detects luminance and chromaticity of the reflected light that is imaged onto the light receiving elements, whereby read image data based on an image of the original surface is generated.

The image forming unit (printing device) 62 is a general-purpose laser printer, and is provided with a photo-conductor, an electrostatic charger, an exposing device, a developing device, a fixing device, etc., and prints an image (print image) corresponding to print image data on a recording paper (sheet) or the like. However, the image forming unit 62 may be formed by an ink jet printer instead of the laser printer.

In addition, although detailed description is omitted, the image forming unit 62 is provided with a color print function, and includes image forming stations each including the photo-conductor, the electrostatic charger, the developing device, etc. for each color of Y (yellow), M (magenta), C (cyan) and K (black) are formed.

The facsimile communication unit 74 includes a facsimile modem, a network control unit (NCU) and a coding/decoding unit. Based on the facsimile communication standard, the facsimile modem modulates coded image data into an analog signal of a format suitable for transmission on the facsimile communication network, and acquires the coded image data by decoding the analog signal form other apparatus. The network control unit is connected to a facsimile telecommunication network via a telephone line, a circuit switch, etc. The network control unit is provided in order to connect the facsimile modem to the facsimile telecommunication network, and performs a circuit control to close and open the facsimile telecommunication network. Furthermore, according to a predetermined facsimile communication protocol, the network control unit transmits and receives image data, control signals, etc., and performs automatic call processing and automatic incoming call processing of the facsimile communication. The coding/decoding unit encodes the image data into a predetermined format. The coded data is temporarily stored by the auxiliary storage 56, and is transmitted to other apparatus by the facsimile communication under instructions of the CPU 52. Moreover, the coding/decoding unit performs processing that restores the data transmitted from other apparatus through the facsimile communication into the original format by decoding the data.

In addition, the electric structure of the image forming apparatus 12 shown in FIG. 3 is a mere example, and should not need to be limited to this.

In such the image forming system 10, the print data including data for printing (print target data) and data of job conditions is generated in the information processing apparatus 14, and the print data is transmitted to the image forming apparatus 12, and print processing (print job) is executed in the image forming apparatus 12 according to the print data.

The print target data includes image data, document data, etc. stored in the information processing apparatus 14, for example.

The job conditions include conditions related to a normal print function (normal print conditions), such as the number of copies to print, original paper size, output paper size, original orientation, color mode, single-sided/double-sided print, magnification, presence/absence of staple processing, presence/absence of page aggregation, etc. When the print job is to be executed, a GUI (graphical user interface) screen of the printer driver for setting the normal print conditions is displayed on the display 36 of the information processing apparatus 14. In addition, since the technology of setting the normal print conditions via the GUI screen is a well-known technology, and has nothing to do with an essential portion of the present invention directly, a detailed description thereof is omitted here.

When the image forming apparatus 12 acquires the print data, data (print image data) of an image for print (print image) is generated, which is obtained through image processing applied to the print target data included in the print data. The print image data is image data that is generated according to the print conditions such as the color mode, the magnification, the page aggregation, etc. and the print conditions are reflected to the print target data. Moreover, the print image data is included in the print data.

Moreover, in the image forming system 10 of this first embodiment, a registration print function and a print data transmission function can be set as a function of the print job (print function).

The registration print function means a function that the print data from the information processing apparatus 14 is temporarily stored in the image forming apparatus 12 that serves as a parent apparatus, and thereafter, the print data stored in the parent apparatus is received by any one of a plurality of child apparatuses according to an operation of an operation panel (input device 70) thereof so as to be printed. That is, the registration print function is a function for utilizing one of the plurality of image forming apparatuses 12 as a print server.

Therefore, in the image forming system 10 of this first embodiment, as shown in FIG. 4 , any one image forming apparatus 12 out of the plurality of image forming apparatuses 12 is set in advance as the parent apparatus 12 x that is an example of the first image forming apparatus, and the image forming apparatuses 12 other than parent apparatus 12 x are set as child apparatuses 12 y each of which is an example of a second image forming apparatus. In addition, subscripts “x” and “y” applied to the reference numerals are subscripts for distinguishing between the parent apparatus and the child apparatus, and for example, in a case of a CPU included in the parent apparatus 12 x, it is indicated as a CPU 52 x, and so on. However, in the following, when it is not necessary to distinguish the parent apparatus 12 x and the child apparatus 12 y, the subscript is arbitrarily omitted so as to refer to inclusively.

If the registration print function is set in the image forming system 10, print data including a command for instructing the parent apparatus 12 x to save the print data (save instruction) is transmitted to the parent apparatus 12 x. In the parent apparatus 12 x that receives the print data including the save instruction, this print data is saved in the auxiliary storage 56 x. Then, when a print instruction is received in a certain child apparatus 12 y from a user, the print data is transferred to that child apparatus 12 y from the parent apparatus 12 x, and the print job related to the print data is executed by the child apparatus 12 y. That is, in the registration print function, the parent apparatus 12 x is used as a print server.

Moreover, the print data transmission function means a function that when the print job is executed in a certain image forming apparatus 12, the print image data included in the print data concerning the print job may be transmitted to a predetermined destination apparatus. The print image data is transmitted by facsimile communication, or transmitted by electronic mail (E-mail) with being attached thereto. A transmission destination apparatus corresponds to the image forming apparatus 12 other than the image forming apparatus having executed the print job (i.e., a further image forming apparatus 12), the information processing apparatuses 14 and an external apparatus capable of communicating via the network 16 or the like.

As shown in FIG. 5 , The GUI of the printer driver of this embodiment includes a function setting screen 100 in addition to the various kinds of setting screens for setting the normal print conditions.

The function setting screen 100 is a screen for setting conditions related to the registration print function and the print data transmission function (conditions other than the normal print conditions) out of the job conditions, and includes a setting portion 102 and an indication portion 104.

The setting portion 102 includes a setting icon 102 a for the registration print function and a setting icon 102 b for the print data transmission function.

The setting icon 102 a of the registration print function is an icon for setting enabling/disabling of the registration print function, and the setting icon 102 b is an icon for displaying a transmission destination setting screen 120 (see FIG. 6 ) capable of setting the content of the print data transmission function.

A check box 102 c is provided in the setting icon 102 a of the registration print function. If operating the setting icon 102 a (including the check box 102 c) for the registration print function in a state where the check mark is not displayed in the check box 102 c, a check mark becomes to be displayed in the check box 102 c. On the other hand, if operating the setting icon 102 a for the registration print function in a state where the check mark is being displayed in the check box 102 c, the check mark becomes not to be displayed.

When the check mark is displayed in the check box 102 c, the registration print function is enabled, and when the check mark is not displayed in the check box 102 c, the registration print function is disabled. Therefore, the user can switch enabling/disabling of the registration print function by operating the setting icon 102 a for the registration print function.

An indication portion 104 is arranged at the lower right of the function setting screen 100, and an OK icon 104 a and a cancel icon 104 b are included in the indication portion 104. The OK icon 104 a is an icon to which a function to settle the content that is set on that screen (here, function setting screen 100) is assigned. The cancel icon 104 b is an icon to which a function to cancel the content that is set on that screen (here, function setting screen 100) is assigned. In addition, when the cancel icon 104 b is selected, the operation screen (here, function setting screen 100) having been displayed till that time is closed, and another operation screen (for example, a setting screen for setting the normal print conditions) or an initial screen (home screen) are displayed. The same is applied also to an OK icon 128 a and a cancel icon 128 b, an OK icon 144 a and a cancel icon 144 b, and an OK icon 164 a and a cancel icon 164 b all described later.

If the icon 102 b for setting the print data transmission function is operated in the function setting screen 100, a transmission destination setting screen 120 as shown in FIG. 6 is displayed on the display 36.

The transmission destination setting screen 120 is a screen for setting enabling/disabling of the print data transmission function, and for setting a transmission destination apparatus when the print data transmission function is enabled.

The transmission destination setting screen 120 includes a setting portion 122, a candidate display portion 124, a transmission destination display portion 126 and an indication portion 128. In addition, the indication portion 128 includes the OK icon 128 a and the cancel icon 128 b.

The setting portion 122 includes a first icon 122 a, a second icon 122 b, a third icon 122 c and a fourth icon 122 d.

The first icon 122 a is an icon to which a function to set enabling/disabling of the print data transmission function is assigned. A check box 122 e is provided in the first icon 122 a. If the first icon 122 a (including the check box 122 e) is operated, a check mark is displayed in the check box 122 e, or a check mark is not displayed. When the check mark is displayed in the check box 122 e, the print data transmission function is enabled, and when the check mark is not displayed in the check box 122 e, the print data transmission function is disabled. That is, the user can switch enabling/disabling of the print data transmission function by operating the first icon 122 a.

The second icon 122 b is an icon to which a function of acquiring destination information (mail address, facsimile number, etc.) of an apparatus that serves as a candidate (candidate apparatus) of the transmission destination apparatus is assigned. In this embodiment, the data of the destination information of the candidate apparatus (data of an address book including the destination information) is stored in the parent apparatus 12 x, and if the second icon 122 b is operated, the data of the destination information of the candidate apparatus (destination information data) is transferred to the information processing apparatus 14 from the parent apparatus 12 x. If the information processing apparatus 14 acquires the destination information data of the candidate apparatus, information of the candidate apparatus (including a device ID, name of the candidate apparatus, etc.) is listed and displayed in a candidate display portion 124 as shown in FIG. 6 . On the other hand, in a state where the information processing apparatus 14 does not acquire the destination information data of the candidate apparatus, the information of the candidate apparatus is not displayed in the candidate display portion 124.

In addition, the destination information data of the candidate apparatus may be stored in the information processing apparatus 14. In this case, the information of the candidate apparatus may be displayed from the beginning, and the second icon 122 b may be omitted.

The third icon 122 c is an icon to which a function to select a transmission destination apparatus out of the candidate apparatuses (adds a transmission destination apparatus) is assigned. Specifically, when the third icon 122 c is operated in a state where at least one apparatus out of the candidate apparatuses displayed in the candidate display portion 124, the apparatus being currently selected is set as the transmission destination apparatus. Information on the apparatus that is set as the transmission destination apparatus is listed and displayed in the transmission destination display 126.

In addition, a pattern or suitable color is applied to a portion corresponding to the information on the apparatus (apparatus under selection) selected among the candidate apparatuses displayed on the candidate display portion 124. Accordingly, the user can recognize the apparatus being selected by that user.

The fourth icon 122 d is an icon to which a function to delete the transmission destination apparatus is assigned. Specifically, when the fourth icon 122 d is operated in a state where at least one apparatus out of the transmission destination apparatuses displayed in the transmission destination display portion 126, the apparatus being currently selected is removed from the transmission destination apparatus (the setting of the transmission destination apparatus is released). Information on the apparatus removed from the transmission destination apparatus is deleted from the transmission destination display portion 126.

In addition, when the print data transmission function is disabled, the second icon 122 b, the third icon 122 c and the fourth icon 122 d may be disabled so as not to be selected.

If the OK icon 128 a is operated in a state where the print data transmission function is enabled and one or more transmission destination apparatuses are set, the information processing apparatus 14 generates data (transmission instruction data) of a command (transmission instruction) to transmit the print image data to the transmission destination apparatus utilizing the print data transmission function. This transmission instruction data is included in the print data.

Then, as described above, the print data for the print job utilizing the registration print function is transmitted to the parent apparatus 12 x from the information processing apparatus 14 to be held in the parent apparatus 12 x. Thereafter, if the user performs an operation for utilizing the registration print function while going a placing location of an arbitrary child apparatus 12 y (child apparatus 12 y for outputting), a print data selection screen 140 as shown in FIG. 7 is displayed on the display 72 y of the child apparatus 12 y for outputting.

The print data selection screen 140 is a screen for selecting the print data for outputting out of the print data concerning the print job utilizing the registration print function, and includes a plurality of selecting icons 142 and indication portion 144. Moreover, in the print data selection screen 140, a message (notification text) for prompting selection of the print data is displayed, for example, “Please select print data”. In addition, the indication portion 144 includes the OK icon 144 a and the cancel icon 144 b.

Each of the plurality of selection icons 142 corresponds to each of a plurality of printing data currently held in the parent apparatus 12 x. A character string for identifying corresponding print data (for example, a data name of the print data, a creator, a created date and time, date and time registered in the parent apparatus 12 x, etc.) is displayed in each of the plurality of selection icons 142. In an example shown in FIG. 7 , four print data are held in the parent apparatus 12 x, and four selection icons 142 a-142 d respectively corresponding to the four print data are displayed in the print data selection screen 140.

The user can select the print data that he/she want to output by operating the selection icon 142.

Then, the selection icon 142 operated by the user becomes in a selected state. If the OK button 146 a is operated in a state where any one of the plurality of selection icons 142 is selected, the print data corresponding to the selection icon 142 in a selected state is settled as the print data for outputting (dealt with as the print data for outputting). Hereinafter, a series of user operations until the print data for outputting is settled may be called a print instruction operation.

If the print data for outputting is settled, the child apparatus 12 y for outputting transmits a print command (print instruction) of the print job concerning the print data for outputting to the parent apparatus 12 x. The parent apparatus 12 x transmits the print data for outputting concerning the print instruction to the child apparatus 12 y for outputting when receiving the print instruction.

When transmission instruction data is not included in the print data for outputting, the parent apparatus 12 x transmits the print data for outputting to the child apparatus 12 y for outputting as it is.

On the other hand, when transmission instruction data is included in the print data for outputting, the parent apparatus 12 x deletes the transmission instruction data from the print data for outputting, and transmits the print data not including the transmission instruction data to the child apparatus 12 y for outputting and transmits the print image data included in the print data for outputting to the transmission destination apparatus.

The child apparatus 12 y for outputting executes the print job according to the print data for outputting when acquiring (receiving) the print data for outputting.

The data of the candidate apparatus and the transmission destination information are managed on a destination information table (address book) as shown in FIG. 8 , for example. The destination information table is created in advance and stored in a predetermined storing location such as the auxiliary storage 56 x of the parent apparatus 12 x, the auxiliary storage 26 of the information processing apparatus 14 or an external server that the information processing apparatus 14 can access, etc. The destination information table is stored in the auxiliary storage 56 of the parent apparatus 12 x in this embodiment.

As shown in FIG. 8 , in the destination information table, the contents (for example, e-mail address, facsimile number) of a destination to which the print image data can be transmitted are described corresponding to inherent identification information (device ID) assigned to each of the apparatuses that may serve candidates for the transmission destination apparatus.

In addition, although a character string, a symbol, a pattern or the like corresponding to the identification information and the destination is described in each column of the destination information table shown in FIG. 8 , these contents are only created and used by internal processing in the information processing apparatus 14 and the parent apparatus 12 x. Therefore, the contents described in each column of the destination information table may be described by symbols or the like that cannot be deciphered by humans.

In addition, in the image formation system 10 of this embodiment, when the setting processing of the transmission destination apparatus is executed in the information processing apparatus 14, and when the print image data is transmitted to the transmission destination apparatus from the parent apparatus 12 x, the destination information table is used.

FIG. 11 is a flowchart showing an example of transmission processing of the CPU 52 x of the parent apparatus 12 x. This transmission processing is started when receiving a print instruction.

As shown in FIG. 11 , if the transmission processing is started, the CPU 52 x determines, in a step S1, whether the transmission instruction data is included in the print data for outputting concerning the print instruction. If “NO” is determined in the step S1, that is, if it is determined that the transmission instruction data is not included in the print data for outputting, the print data for outputting is transmitted to the child apparatus 12 y for outputting in the step S3, and then, the transmission processing is ended.

On the other hand, if “YES” is determined in the step S1, that is, it is determined that the transmission instruction data is included in the print data for outputting, in a step S5, the print data for outputting from which the transmission instruction data is deleted is transmitted to the child apparatus 12 y for outputting, and in a step S7, the print image data included in the print data for outputting is transmitted to a transmission destination apparatus, and then, the transmission processing is ended.

FIG. 12 is a flowchart showing an example of the print processing of the CPU 52 y of the child apparatus 12 y. This print processing is started when a print instruction operation is received by the child apparatus 12 y.

As shown in FIG. 12 , if the print processing is started, the CPU 52 y transmits the print instruction to the parent apparatus 12 x in a step S31, and determines, in a step S33, whether the print data is received. If “NO” is determined in the step S33, that is, if it is determined that the print data is not received, the process returns to the step S33. On the other hand, if “YES” is determined in the step S33, that is, if it is determined that the print data is received, the print job is executed according to the print data in a step S35, and then, the print processing is ended.

In this first embodiment, when receiving the print instruction of the print data, the parent apparatus 12 x transmits the print data to the child apparatus 12 y for outputting, and transmits the print image data included in the print data to the transmission destination apparatus when the transmission instruction data is included in the print data. Therefore, the user can perform the print processing by a desired image forming apparatus (child apparatus 12 y), and can transmit the print image to a desired transmission destination apparatus simultaneously with the print processing. Therefore, it is possible to improve convenience for the user.

Second Embodiment

An image forming system 10 according to the second embodiment is the same or similar to the image forming system 10 according to the first embodiment except that a transmission result of the print image data is notified to the user on the child apparatus 12 y for outputting when the print image data included in the print data for outputting is transmitted to the transmission destination apparatus, and therefore, only the contents different from those of the first embodiment will be described while omitting duplicate description.

In the second embodiment, when the transmission instruction data is included in the print data for outputting, the parent apparatus 12 x transmits the print data for outputting from which the transmission instruction data is deleted to the child apparatus 12 y for outputting, and the print image data included in the print data for outputting to the transmission destination apparatus, and data of the transmission result of the print image data (transmission result data) to the child apparatus 12 y for outputting.

The child apparatus 12 y for outputting notifies a user of the transmission result of the print image data when acquiring (receiving) the transmission result of the print image data. For example, as shown in FIG. 13 , a notification screen 160 for notifying the user of the transmission result of the print image data is displayed on the display 72 y. That is, the notification of the transmission result of the print image data is notified on the screen.

The notification screen 160 includes a notification text 162 and an indication portion 164. In addition, the indication portion 164 includes the OK icon 164 a and the cancel icon 164 b.

The notification text 162 is a message for notifying to the user that the print image data included in the print data for outputting has been transmitted to the transmission destination apparatus, and includes, for example, “The print image data has been transmitted correctly”. In addition, instead of or in addition to the screen notification like the notification screen 160, voice notification that the print image data included in the print data for outputting has been transmitted to the transmission destination apparatus may be issued.

Moreover, in the second embodiment, in order to implement an operation as described above, the control program for the image forming apparatus includes a notification program for notifying the user of the transmission result of the print image data. The notification program includes a program for transmitting the transmission result of the print image data to the child apparatus 12 y for outputting, a program for performing the screen notification and/or voice notification when the transmission result of the print image data is received, etc.

In the following, transmission processing and print processing in the second embodiment will be described using a flowchart; however, duplicate contents will be omitted or briefly described by applying the same reference numerals to the same processing as the transmission processing and the print processing described in the first embodiment.

FIG. 14 is a flowchart showing a part of an example of the transmission processing in the second embodiment. As shown in FIG. 14 , if the transmission processing is started, the CPU 52 x of the parent apparatus 12 x transmits the print image data to the transmission destination apparatus in a step S7, and transmits transmission result data to the child apparatus 12 y for outputting, and then, the transmission processing is ended.

In addition, since the contents of the processing up to the step S7 are the same as those of the first embodiment, duplicate description is omitted.

FIG. 15 is a flowchart showing a part of an example of the print processing in the second embodiment. As shown in FIG. 15 , if the print processing is started, the CPU 52 y of the child apparatus 12 y executes the print job according to the print data in a step S35, and determines, in a step S71, whether the transmission result data is received. If “YES” is determined in the step S71, that is, if it is determined that the transmission result data is received, the transmission result data of the print image data is notified to the user in a step S73, and then, the print processing is ended.

On the other hand, if “NO” is determined in the step S71, that is, if it is determined that the transmission result data is not received, it is determined, in a step S75, whether a predetermined time period (for example, 30 to 120 seconds) elapses since the print job is started or the print job is ended. If “NO” is determined in the step S75, that is, if it is determined that the predetermined time period does not elapse, the process returns to the step S71. On the other hand, if “YES” is determined in the step S75, that is, if it is determined that the predetermined time period elapses, the print processing is ended.

In addition, since the contents of the processing up to the step S35 is the same as those of the first embodiment, the description is omitted.

According to this second embodiment, it is possible to make the user recognize the transmission result of the print image data, and therefore, convenience for the user can be further improved.

Although a third embodiment and a fourth embodiment according to the present invention will be described in the following, the third embodiment and the fourth embodiment use the image forming apparatus 12 and the information processing 14 respectively having the same or similar structure to those of the first embodiment and the second embodiment, and therefore, in the following description, duplicate description with the description of the first embodiment and the second embodiment will be omitted.

Third Embodiment

Moreover, also in the image forming system 10 of this third embodiment, a registration print function and a print data transmission function can be set as a function (print function) of a print job as described previously.

The print data transmission function in this third embodiment is a function that transmits the print image data based on the print data concerning the print job to a predetermined apparatus (a second external apparatus) when the print job is executed in an certain image forming apparatus 12. That is, the print data transmission function is a function that performs collectively a print and transmission of the print image data. The print image data may be transmitted by a facsimile communication or by an E-mail with being attached thereto.

The second external apparatus corresponds to the image forming apparatus 12 other than the image forming apparatus 12 that executes the print job, the information processing apparatus 14, other external apparatus capable of performing communication via the network 16, etc. Therefore, there is an occasion that the first external apparatus that is a transmission source of the print data and the second external apparatus that is a transmission destination of the print image data are the same apparatus. Designation of the second external apparatus by a user is performed in the information processing apparatus 14 by reading (acquiring) the address book (destination information table, see FIG. 8 ) of the image forming apparatus 12 that transmits the print data.

In the image forming system 10, if the print data transmission function is set, the print data including a command instructing to transmit (transmission instruction) the print image data to a predetermined second external apparatus is transmitted to the image forming apparatus 12. This transmission instruction includes ID information described on the address book and date and time information that the image forming apparatus 12 acquires the address book. A reason why the date and time information is included in the transmission instruction is for preventing erroneous transmission by preventing confusion with an address book owned by another image forming apparatus 12. The image forming apparatus 12 that receives the print data including transmission instruction executes the print job using the print image data generated based on the print data, and reads the destination information of the second external apparatus based on the ID information included in the transmission instruction with reference to the own address book, thereby to transmit the print image data to the destination (that is, designated second external apparatus).

Moreover, in the image forming system 10, if both of the registration print function and the print data transmission function are set, the print data including a save instruction and a transmission instruction to the second external apparatus is transmitted to the parent apparatus 12 x. Although the ID information and the date and time information are included in this transmission instruction, these information are based on the address book of the parent apparatus 12 x. Therefore, when receiving the print instruction from a user in a certain child apparatus 12 y, even if the parent apparatus 12 x transmits the print data to the child apparatus 12 y as it is, the child apparatus 12 y cannot execute the transmission processing (print data transmission function) of the print image data to the second external apparatus.

Therefore, in this third embodiment, in transmitting the print data to the child apparatus 12 y from the parent apparatus 12 x, the parent apparatus 12 x transmits to the child apparatus 12 y the print data by adding the destination information of the designated second external unit. That is, the destination information is made to be included in the transmission instruction. At this time, the ID information and the date and time information originally included in the transmission instruction may be deleted. The child apparatus 12 y that receives the print data including the destination information executes the print processing using the print image data generated based on the print data, and transmits the print image data to that destination (i.e., the designated second external apparatus) utilizing the destination information included in the transmission instruction.

In addition, procedure of setting the registration print function and the print data transmission function in the GUI of the printer driver displayed on the display 36 of the information processing apparatus 14 that is an example of the first external apparatus is as having described previously.

FIG. 16 is a flowchart showing an example of the print transmission processing (parent apparatus operation) executed by the CPU 52 x of the parent apparatus 12 x. In addition, the CPU 52 x of the parent apparatus 12 x functions as a first transmission determination unit and a first communication control unit, etc. in the present invention. This print transmission processing is started when the print data is received from the information processing apparatus 14.

As shown in FIG. 16 , if the print transmission processing is started, the CPU 52 x determines, in a step S101, whether a save instruction is included in the print data received from the information processing apparatus 14. That is, it is determined whether the registration print function is set.

If “NO” is determined in the step S101, that is, if the save instruction is not included in the print data, the received print data is output in a step S103. That is, the CPU 52 x transmits a control signal to the image forming unit 62 x etc. so as to form an image based on the print data on the recording medium. In a subsequent step S105, it is determined whether the transmission instruction is included in the received print data. That is, it is determined whether the print data transmission function is set. If “NO” is determined in the step S105, that is, if the transmission instruction is not included in the print data, the print transmission processing is ended. On the other hand, if “YES” is determined in the step S105, that is, if the transmission instruction is included in the received print data, image transmission to the designated second external apparatus is performed in a step S107. That is, the CPU 52 x reads the destination information (email address, etc.) corresponding to the device ID included in the transmission instruction from the own address book (destination information table), and transmits the print image data based on the print data to the destination (the second external apparatus). When the processing of the step S107 is executed, this print transmission processing is ended.

On the other hand, if “YES” is determined in the step S101, that is, if the save instruction is included in the print data, the received print data is saved (stored) in the auxiliary storage 56 x in a step S109. In a subsequent step S111, it is determined whether the print data is requested by the child apparatus 12 y. If “NO” is determined in the step S111, that is, if there is no request of the print data from the child apparatus 12 y, the print transmission processing is ended. On the other hand, if “YES” is determined in the step S111, that is, if the print data is requested by the child apparatus 12 y, the process proceeds to a step S113.

In the step S113, it is determined whether the transmission instruction is included in the received print data. If “NO” is determined in the step S113, that is, if the transmission instruction is not included in the print data, after the print data is transmitted to the child apparatus 12 y in a step S115, the print transmission processing is ended. On the other hand, if “YES” is determined in the step S115, that is, if the transmission instruction is included in the received print data, the destination information corresponding to the device ID included in the transmission instruction is read from the own address book in a step S117. In a subsequent step S119, the print data to which the destination information is added is transmitted to the child apparatus 12 y. When the processing of the step S119 is executed, this print transmission processing is ended.

FIG. 17 is a flowchart showing an example of the print transmission processing (child apparatus operation) executed by the CPU 52 y of the child apparatus 12 y. In addition, the CPU 52 y of the child apparatus 12 y functions as a second transmission determination unit and a second communication control unit in the present invention. The print transmission processing is started when an operation for print instruction utilizing the registration print function from the user is received by the input device 70 y of the child apparatus 12 y.

As shown in FIG. 17 , if the print transmission processing is started, the CPU 52 y requests the print data to the parent apparatus 12 x in a step S131. In a subsequent step S133, it is determined whether the print data is received. If “NO” is determined in the step S133, that is, if the print data is not received, the process returns to the step S133. On the other hand, if “YES” is determined in the step S133, that is, if the print data is received, the received print data is output in a step S135. That is, the CPU 52 y transmits a control signal to the image forming unit 62 y etc., so as to form an image based on the print data on a recording medium.

In a subsequent step S137, it is determined whether the transmission instruction is included in the received print data. That is, it is determined whether the print data transmission function is set. If “NO” is determined in the step S137, that is, if the transmission instruction is not included in the print data, the print transmission processing is ended. On the other hand, if “YES” is determined in the step S137, that is, if the transmission instruction is included in the received print data, the image is transmitted to the designated second external apparatus in a step S139. That is, the CPU 52 y transmits the print image data based on the print data to the destination (the second external apparatus) utilizing the destination information included in the print data. After execution of the processing in the step S139, this print transmission processing is ended.

As described above, in this third embodiment, when the transmission instruction to the second external apparatus is included in the print data received from the information processing apparatus 14, the parent apparatus 12 x adds the destination information of the second external apparatus to the print data so as to transmit to the child apparatus 12 y. The child apparatus 12 y transmits the print image data to the second external apparatus utilizing the destination information added to the print data while forming an image on the recording medium based on the received print data.

Therefore, according to this third embodiment, by utilizing the print data that is transmitted from the information processing apparatus 14 based on the input operation by the user to be saved, it is possible to transmit the print image data to a desired second eternal apparatus at the same time as executing the print operation in the child apparatus 12 y. That is, since the registration print function and the print data transmission function can be appropriately linked, the convenience of the user can be improved.

Fourth Embodiment

Next, an image forming system 10 of the fourth embodiment according to the present invention will be described. In the fourth embodiment, the processing after the child apparatus 12 y transmits the print image data to the second external apparatus differs from that of the above-described third embodiment. Since except the above, the fourth embodiment is the same as the third embodiment, duplicate description will be omitted.

In the image forming system 10 of the fourth embodiment, the child apparatus 12 y transmits (notifies) a transmission result (transmission result information) to the parent apparatus 12 x after transmitting the print image data to the second external apparatus. The parent apparatus 12 x saves (stores) the transmission result as a job log in the own auxiliary storage 56 x when the transmission result is received from the child apparatus 12 y. The user can know the transmission result of transmitting the print image data to the second external apparatus from the child apparatus 12 y with reference to the job log of the parent apparatus 12 x by accessing the parent apparatus 12 x from the information processing apparatus 14. In addition, the transmission result to the second external apparatus by the child apparatus 12 y is saved in the parent apparatus 12 x, and can also be saved as a job log in the child apparatus 12 y.

In the following, an example of the print transmission processing (child apparatus operation) executed by the CPU 52 y of the child apparatus 12 y in the fourth embodiment will be described using a flowchart of FIG. 18 . However, since the contents of the processing from the step S131 to the step S139 are the same as those of the third embodiment, duplicate description is omitted.

As shown in FIG. 18 , the CPU 52 y of the child apparatus 12 y transmits a result of the image transmission to the parent apparatus 12 x in a step S141 after the step S139. For example, when the transmission of the print image data to the second external apparatus is completed, the transmission result indicating that the transmission is completed is transmitted, and when the transmission of the print image data to the second external apparatus is not completed even if a predetermined time period elapses, the transmission result indicative of not having completed (i.e., occurring of transmission error) is transmitted. When the processing of the step S141 is executed, this print transmission processing is ended.

In addition, although illustration is omitted, the CPU 52 x of the parent apparatus 12 x saves (stores) the transmission result received from the child apparatus 12 y in the auxiliary storage 56 x.

According to the fourth embodiment, since the transmission result of the print image data in the child apparatus 12 y can be confirmed by referring to the job log of the parent apparatus 12 x, it is possible to further improve the convenience for the user.

In addition, specific configurations etc. described in the above-described embodiments are mere examples and can be appropriately changed according to actual products. Furthermore, as long as the same effect or result is obtained, an order of respective steps shown in the flow charts indicated in the above-described embodiments may be appropriately changed.
